Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“ U.S. GAAP ”) and applicable rules and regulations of the Securities and Exchange Commission (“ SEC ”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, which was filed with the SEC on March 2, 2015 (“ 2014 Form 10-K ”). The condensed consolidated balance sheet as of December 31, 2014 , included herein, was derived from the audited financial statements as of that date but does not include all disclosures, including notes required by U.S. GAAP . In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial positions, results of operations and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2015 or any future period. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates estimates on a regular basis including those relating to revenue recognition, the allowance for doubtful accounts, goodwill, intangible assets, the valuation of deferred income taxes, stock-based compensation and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s condensed consolidated financial statements and footnotes. Significant Accounting Policies The Company’s significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in its 2014 Form 10-K . There have been no significant changes to these policies during the six months ended June 30, 2015 . Other Income, Net Other income, net consisted of the following: Three Months ended June 30, Six Months ended June 30, 2015 2014 2015 2014 (in thousands) Interest income $ 172 $ 144 $ 331 $ 266 Net realized loss on investments — (8 ) — (7 ) Interest expense (19 ) (27 ) (46 ) (50 ) Total other income, net $ 153 $ 109 $ 285 $ 209 Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss) . Other comprehensive income (loss) includes certain changes in equity that are excluded from net income, specifically unrealized gains (losses) on available-for-sale investments. Except for net realized loss on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income (loss) that affected net income during the three and six months ended June 30, 2015 and 2014 . Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“ FASB ”) issued Accounting Standards Update (“ ASU ”) No. 2014-09, Revenue from Contracts with Customers (“ ASU 2014-09 ”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 also requires significantly expanded disclosures about revenue recognition. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. On July 9, 2015, the FASB Board voted to defer the effective date of ASU 2014-09 by one year. The new effective date for public entities will be for fiscal years, and interim periods within those years, beginning after December 15, 2017, but entities will be permitted to early adopt the standard as of the original effective date. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (“ ASU 2015-05 ”), which clarifies the circumstances under which a cloud computing customer would account for the arrangement as a license of internal-use software. ASU 2015-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share of Common Stock	Net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding during the period. Diluted net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding and potential shares of common stock during the period. Potential shares of common stock include dilutive shares attributable to the assumed exercise of stock options, restricted stock unit awards (“ RSU s”), performance-vesting RSUs , performance share awards (“ Performance Awards ”) and Employee Stock Purchase Plan (“ ESPP ”) shares using the treasury stock method, if dilutive. The components of net income per share of common stock were as follows: Three Months ended June 30, Six Months ended June 30, 2015 2014 2015 2014 (in thousands, except share and per share amounts) Net income $ 7,630 $ 4,724 $ 11,214 $ 5,506 Basic shares: Weighted average common shares outstanding 29,092,149 27,617,142 28,931,042 27,479,035 Diluted shares: Weighted average shares used to compute basic net income per share 29,092,149 27,617,142 28,931,042 27,479,035 Effect of potentially dilutive securities: Employee stock options, RSUs, performance-vesting RSUs, Performance Awards and ESPP shares 1,715,268 1,671,786 1,712,029 1,713,832 Weighted average shares used to compute diluted net income per share 30,807,417 29,288,928 30,643,071 29,192,867 Net income per share: Basic $ 0.26 $ 0.17 $ 0.39 $ 0.20 Diluted $ 0.25 $ 0.16 $ 0.37 $ 0.19 The following potential common shares were excluded from the computation of diluted net income per share, as their effect would have been anti-dilutive: Three Months ended June 30, Six Months ended June 30, 2015 2014 2015 2014 Employee stock options and awards 190,186 1,305,110 395,182 1,051,298 Performance-vesting RSUs and Performance Awards are included in the diluted shares outstanding for each period if the established performance criteria have been met at the end of the respective periods. However, if none of the required performance criteria have been met for such awards, the Company includes the number of shares that would be issuable if the end of the reporting period were the end of the contingency period. Accordingly, in addition to the employee stock options and awards noted above, 186,312 and 100,000 shares underlying performance-vesting RSUs and Performance Awards were excluded from the dilutive shares outstanding for each of the three and six months ended June 30, 2015 and 2014 , respectively.

Financial Instruments and Fair Value Measurements [Abstract]
Financial Instruments and Fair Value Measurements	Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following three categories: Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities. Level 2 — Valuations based on other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Valuations based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the assets or liabilities. The following tables set forth by level within the fair value hierarchy the Company’s financial assets that were accounted for at fair value on a recurring basis, according to the valuation techniques the Company used to determine their values: Fair value at Fair value measurements using inputs considered as June 30, 2015 Level 1 Level 2 Level 3 (in thousands) Money market funds $ 4,266 $ 4,266 $ — $ — Certificates of deposit 14,776 — 14,776 — Corporate notes and obligations 28,200 — 28,200 — Municipal obligations 1,943 — 1,943 — U.S. government and government agency obligations 62,316 17,291 45,025 — $ 111,501 $ 21,557 $ 89,944 $ — Fair value at Fair value measurements using inputs considered as December 31, 2014 Level 1 Level 2 Level 3 (in thousands) Money market funds $ 3,220 $ 3,220 $ — $ — Certificates of deposit 14,962 — 14,962 — Corporate notes and obligations 29,035 — 29,035 — Municipal obligations 3,155 — 3,155 — U.S. government and government agency obligations 60,879 16,946 43,933 — $ 111,251 $ 20,166 $ 91,085 $ — Financial instruments include cash, cash equivalents and investments including investment-grade interest-bearing securities, such as money market accounts, certificates of deposit, commercial paper, corporate bonds, municipal and government agency obligations and guaranteed obligations of the U.S. government . The Company classifies its money market funds that are specifically backed by debt securities and U.S. government obligations as Level 1 instruments due to the use of observable market prices for identical securities that are traded in active markets . When the Company uses observable market prices for identical securities that are traded in less active markets , the Company classifies its marketable financial instruments as Level 2. When observable market prices for identical securities are not available , the Company prices its marketable financial instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs . The Company corroborates non-binding market consensus prices with observable market data as such data exists . At June 30, 2015 and December 31, 2014 , the Company did not have any assets or liabilities that were valued using Level 3 inputs. For the three and six months ended June 30, 2015 and 2014 , there were no transfers of financial instruments among Level 1, Level 2 or Level 3 classifications. For the three and six months ended June 30, 2015 the Company recognized interest income from financial instruments of $0.2 million and $0.3 million , respectively. For the three and six months ended June 30, 2014 the Company recognized interest income from financial instruments of $0.1 million and $0.3 million , respectively. Gross realized gains and gross realized losses from the sale of investments were not significant during the three and six months ended June 30, 2015 and 2014 . The carrying amounts, gross unrealized gains and losses and estimated fair value of cash and cash equivalents and both short-term and long-term investments consisted of the following: June 30, 2015 Amortized cost Unrealized gains Unrealized losses Carrying or fair value (in thousands) Cash and cash equivalents: Cash $ 30,652 $ — $ — $ 30,652 Money market funds 4,266 — — 4,266 $ 34,918 $ — $ — $ 34,918 Investments: Corporate notes and obligations $ 28,226 $ 17 $ (43 ) $ 28,200 Certificates of deposit 14,756 24 (4 ) 14,776 Municipal obligations 1,939 4 — 1,943 U.S. government and government agency obligations 62,279 56 (19 ) 62,316 $ 107,200 $ 101 $ (66 ) $ 107,235 December 31, 2014 Amortized cost Unrealized gains Unrealized losses Carrying or fair value (in thousands) Cash and cash equivalents: Cash $ 23,536 $ — $ — $ 23,536 Money market funds 3,220 — — 3,220 $ 26,756 $ — $ — $ 26,756 Investments: Corporate notes and obligations $ 29,071 $ 4 $ (40 ) $ 29,035 Certificates of deposit 14,972 11 (21 ) 14,962 Municipal obligations 3,149 6 — 3,155 U.S. government and government agency obligations 60,934 18 (73 ) 60,879 $ 108,126 $ 39 $ (134 ) $ 108,031 The following table shows the gross unrealized losses and the related fair values of the Company’s investments that have been in a continuous unrealized loss position: June 30, 2015 Less than 12 Months 12 Months or Greater Total Fair Value Unrealized losses Fair Value Unrealized losses Fair Value Unrealized losses (in thousands) Corporate notes and obligations $ 15,810 $ (43 ) $ — $ — $ 15,810 $ (43 ) Certificates of deposit 1,872 (4 ) — — 1,872 (4 ) U.S. government and government agency obligations 13,260 (19 ) — — 13,260 (19 ) $ 30,942 $ (66 ) $ — $ — $ 30,942 $ (66 ) December 31, 2014 Less than 12 Months 12 Months or Greater Total Fair Value Unrealized losses Fair Value Unrealized losses Fair Value Unrealized losses (in thousands) Corporate notes and obligations $ 19,535 $ (40 ) $ — $ — $ 19,535 $ (40 ) Certificates of deposit 5,735 (21 ) — — 5,735 (21 ) U.S. government and government agency obligations 34,899 (73 ) — — 34,899 (73 ) $ 60,169 $ (134 ) $ — $ — $ 60,169 $ (134 ) The following table summarizes the maturities of the Company’s investments at June 30, 2015 : Carrying or fair value (in thousands) Remainder of 2015 $ 28,925 2016 44,959 2017 27,175 2018 6,176 Total $ 107,235 Actual maturities may differ from the contractual maturities because borrowers may have the right to call or prepay certain obligations.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	The Company computes its interim provision for income taxes by applying the estimated annual effective tax rate to the year-to-date income from recurring operations and adjust the provision for discrete tax items recorded in the period. The Company evaluates and updates its estimated annual effective income tax rate on a quarterly basis. The estimated annual effective tax rate as of June 30, 2015 and 2014 was 42.8% and 35.2% , respectively. The difference between the federal statutory rate of 35% and the Company’s estimated effective tax rate for the three and six months ended June 30, 2015 was primarily due to the Company’s state income tax provision and non-deductible stock-based compensation expenses. The Company’s annual estimated effective tax rate fluctuates quarterly due to the impact of stock based compensation deductions on the Internal Revenue Code (“IRC”) Section 199 deduction. The Company accounts for stock-based compensation pursuant to ASC 718 and uses ASC 740 ordering when determining when excess tax benefits have been realized. The Company realized a tax benefit of $0.9 million and $3.9 million for the three and six months ended June 30, 2015 related to the exercise of employee stock options and the vesting of RSUs, performance-vesting RSUs and Performance Awards. The net income tax benefit in excess of the expenses recorded for financial reporting purposes has been recorded as an increase to additional paid-in capital and is reflected as a financing cash inflow in the condensed consolidated statements of cash flows. The Company’s tax positions are subject to income tax audits by multiple tax jurisdictions. The Company accounts for uncertain tax positions and believes that it has provided adequate reserves for its unrecognized tax benefits for all tax years still open for assessment. The Company also believes that it does not have any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next twelve months. The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability in the balance sheet, and to include the expenses incurred related to such accruals in the provision for income taxes. There were no interest or penalties included in the provision for income taxes during the six months ended June 30, 2015 and 2014 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Leases As of June 30, 2015 , the Company leased seven facilities under operating lease arrangements. The lease expiration dates range from January 2016 to December 2024 . Certain leases contain escalation clauses calling for increased rents. The Company recognizes rent expense on a straight-line basis over the lease period and has recorded deferred rent for the difference between rent payments and rent expense recognized. In July 2015, the Company entered into an amendment to the Company’s existing office lease in Pleasanton, California to expand office space. The term of the lease for the expanded office space in Pleasanton, California commences on January 1, 2016 and ends on December 31, 2024, with payments ranging from $79,000 per month to $103,500 per month. The Company leases certain fixed assets under non-cancelable capital leases with various expiration dates. Future minimum lease payments under non-cancelable operating and capital leases at June 30, 2015 consisted of the following: Capital leases Operating leases (in thousands) 2015 $ 2,039 $ 303 2016 $ 3,717 $ 4,531 2017 482 4,851 2018 — 4,896 2019 — 4,844 2020 — 4,834 Thereafter — 20,407 Total minimum lease payments 6,238 $ 44,666 Less amount representing interest (83 ) Present value of minimum lease payments 6,155 Less current portion (4,009 ) Long-term portion of lease obligations $ 2,146 Legal Proceedings From time to time, the Company is involved in litigation that it believes is of the type common to companies engaged in the Company’s line of business, including commercial disputes and employment issues. As of the date of this Quarterly Report on Form 10-Q, the Company is engaged in an arbitration proceeding with the founder of MortgageCEO, a business we purchased in the first quarter of 2014. The proceeding involves an employment claim against us with respect to, among other things, the vesting of certain restricted stock units granted to the founder of MortgageCEO, and a breach of contract counterclaim and other causes of action. While we are contesting the employment claim vigorously, the outcome of the arbitration is uncertain. Except as discussed above, the Company is not involved in any pending legal proceedings whose outcome the Company expects to have a material adverse effect on its financial position, results of operations or cash flows. However, litigation is unpredictable and excessive verdicts, both in the form of monetary damages and injunctions, could occur. In the future, litigation could result in substantial costs and diversion of resources and the Company could incur judgments or enter into settlements of claims that could have a material adverse effect on its business.

Accounting Policies [Abstract]
Principles of Consolidation [Policy Text Block]	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates estimates on a regular basis including those relating to revenue recognition, the allowance for doubtful accounts, goodwill, intangible assets, the valuation of deferred income taxes, stock-based compensation and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s condensed consolidated financial statements and footnotes.
Significant Accounting Policies [Text Block]	Significant Accounting Policies The Company’s significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in its 2014 Form 10-K . There have been no significant changes to these policies during the six months ended June 30, 2015 .
Comprehensive Income [Policy Text Block]	Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss) . Other comprehensive income (loss) includes certain changes in equity that are excluded from net income, specifically unrealized gains (losses) on available-for-sale investments. Except for net realized loss on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income (loss) that affected net income during the three and six months ended June 30, 2015 and 2014
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“ FASB ”) issued Accounting Standards Update (“ ASU ”) No. 2014-09, Revenue from Contracts with Customers (“ ASU 2014-09 ”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 also requires significantly expanded disclosures about revenue recognition. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. On July 9, 2015, the FASB Board voted to defer the effective date of ASU 2014-09 by one year. The new effective date for public entities will be for fiscal years, and interim periods within those years, beginning after December 15, 2017, but entities will be permitted to early adopt the standard as of the original effective date. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (“ ASU 2015-05 ”), which clarifies the circumstances under which a cloud computing customer would account for the arrangement as a license of internal-use software. ASU 2015-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements.
